While scientists were aware of the larvae’s potential as a substitute, quality and availability were problematic until Champion developed her TruLarv specially bred moths solution at Exeter University.

She said: “The only larvae sources were shops selling fishing bait and pet food. They were dirty, varied genetically and contained antibiotics and hormones that could affect the outcome of experiments.

“We provide standardised, decontaminated larvae that can be used in testing for diseases, poisons and developing new drugs cost-effectively.”
